Hearing Aid

Patent No. EP2491729 (titled "Hearing Aid") was filed by Exsilent Research on Oct 18, 2010. The application was issued on Mar 31, 2021.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
